IMPORTANT. The gas service cock contains a
non-metallic seal so must not be overheated
when making capillary connections.

Refer to Frame 2 for details of the position of the
gas connection.

The principle of the 1:1 gas valve ensures that
the isar range is able to deliver its full output at
inlet pressures well below those required by
BS. 6891.

A boiler gas supply pipe length of 20m and not
less than 15mm O.D. can be connected to the
boiler via the gas service cock union.

Ensure that the gas supply pipe does not foul
the boiler casing.

Refer to Frame 36 or 'Servicing' for details of the
pressure test point position.

GAS CONNECTION

WATER CONNECTIONS - DHW

Note.

The DHW inlet

isolating valve incorporates
a flow regulator / filter. It should
be inspected

to ensure no blockage

is evident.

1. To remove, turn off the valve, undo the

retaining screw and pull out the filter
by grasping the crossbar with pliers.

2. Reassemble in reverse order,

inserting in the direction of the arrow.
